A half century of research details how segregating racial groups in separate schools corresponds with disparities in funding and quality teachers and culturally narrow curricula. But we know little about whether young Latino children have entered less or more segregated elementary schools over the past generation. This article details the growing share of Latino children from low-income families populating schools, 1998 to 2010. Latinos became more segregated within districts enrolling at least 10% Latino pupils nationwide, including large urban districts. Exposure of poor students (of any race) to middle-class peers improved nationwide. This appears to stem in part from rising educational attainment of adults in economically integrated communities populated by Latinos. Children of native-born Latina mothers benefit more from economic integration than those of immigrant mothers, who remain isolated in separate schools. We discuss implications for local educators and policy makers and suggest future research to illuminate where and how certain districts have advanced integration.
